Note di rilascio della versione 1.0

Il programma proposto Abaco Maya è un gioco educativo il cui scopo è di avvicinare l'utente al 'magico' mondo dell'aritmetica Maya.
Esso consta di una generazione pseudocasuale di numeri nella rappresentazione Maya, vigesimale, il compito dell'utente è di trovarne la corrispondente rappresentazione decimale (con cifre arabe).
Naturalmente, il gioco è fornito anche con la variante inversa: generazione pseudocasuale di numeri nella usuale rappresentazione decimale con cifre arabe, affinché l'utente ne costruisca la rappresentazione Maya vigesimale.
